Strengths & weaknesses

Strengths

  • Time to first token as low as 50 ms (causal encoder prefills while you speak)
  • About 2B parameters, in BF16, GGUF, MLX and ONNX
  • Turns spoken requests into tool calls

Weaknesses

  • Voice chat is English only, though it understands 18 languages
  • Not on the AA leaderboard
  • No inference provider hosts it

Not notable: not on AA. Included as a speech-in, speech-out streaming model, but the model card doesn't call it full duplex; drop it if the directory requires full-duplex realtime. languages = 18 (the header figure; the list has 19 entries because it separates British and American English). The licence record matches the LFM Open License v1.0 entry already in models.json.
